Lightburn generates additional cut lines at start of element

LightBurn Software Questions

Hello,
my first post and I have following problem
Light burn generates in the g code a short additional cut line at the start of rectangle . Sometimes straight or with angle
It s cutting a line of 3-4 mm long always at start of a new contour . -

See attached fotos (if I can manage it )

It s definitively in the g code , and it s not from the import of DXF ( double lines) - i check it with my other setup milling router software , and there no such problem

I use light burn 1.4 - and I cut only 1 pass
I can imagine that this a setting somewhere in LB but I was not able to localize it :thinking:
Any advice will be much appreciated

Thank you
Willy

so i check my Light burn SW (one of the CAD PC and the one at the machine ) both have not this lead In or OUT activated…
the question remains… What can be the root cause of this additioanl cutting line ?

some months ago i though it was no more there, suddenly, (also lightburn, same laser cutter ( i must say i add a long pause in between) but it s again definitively again there…
